Description

[Detailed description of the invention] (Industrial application field) The present invention prevents stuffiness due to sweat on the back when carrying the back, and interposes between the back and the backpack to hold the back elastically. It relates to a backpack that has this board.

(Prior Art) Conventionally, for example, a frame is interposed on the outer surface of a backpack of a rucksack, and a backing cloth having a mesh or mesh attached to the outer surface of the frame is applied to the backcloth, the frame, and the back. Attach the perimeter of the backing cloth to the backpack, and attach the backing cloth mesh or mesh body so that a gap is formed between the frame and the backing cloth mesh or mesh body. Rucksacks that provide ventilation between the back surfaces to prevent stuffiness due to sweat on the back are known from Japanese Utility Model Publication No. 55-45778.

(Problems to be solved by the invention) However, this type of structure holds the rucksack elastically with respect to the back on a frame or the like interposed between the back of the rucksack and the back of the backpacker. Since it does not have elasticity, when walking while carrying it, the rucksack does not swing elastically on the back and its weight rests on the back without interruption and fatigue of the backpacker There were problems such as increasing the degree.

(Means for Solving the Problems) In the present invention, the lower side is made of a leaf spring 7 having outwardly curved portions 7 ', 7' at both ends, and a plastic frame is integrally attached to a portion near both sides thereof. A frame plate 3 having a wide gap 2 extending from the front surface to the back surface and having a curved portion so as to be partially in contact with the back surface of the backpack 1 without being in close contact with the back surface; Of the frame plate 3 so that the upper side is joined to the upper side of the frame plate 3 and both ends of the lower side are joined to the outer sides of the curved portions 7 ', 7' of the leaf spring 7, respectively. A back plate 6 composed of a net plate 5 integrally fixed on the front surface side;
It is an object of the present invention to solve such a problem by providing a backpack that is provided with a detachable connection fastener at a required position of a backrest surface of the backpack 1 and a backrest plate 6. .

(Embodiment) A wide gap formed between the frame portions 3 'and 3' from the front surface to the back surface by integrally mounting plastic frame portions 3 'and 3' on the lower side portion made of a leaf spring 7. 2, and the frame portions 3 'and 3' are slightly curved so as not to be entirely in contact with the back surface of the backpack 1 but to be partially in contact therewith;
Similarly, it has a large number of through-holes 4 opening from the front surface to the back surface, and is superposed on the front side of the frame plate 3 and both upper and lower ends are integrally fixed to the frame plate 3 with plastic studs 8. A backing plate 6 composed of a plastic net plate 5 is provided, and a stop ring 12 is attached as a connecting stop at the center of the upper end and both ends of the lower side of the backing surface of the backpack body 1, and the connecting stop is also provided at the center of the lower side. Attachment pieces 13 for fitting the lower side of the frame plate 3 are attached as tools, and bands which can be inserted into the above-mentioned stop ring 12 as connection fasteners at the center of the upper side and both ends of the lower side of the net plate 5 in the backing plate 6 respectively. Each of the strips 14 is attached, and a pair of removable male and female hook-and-loop fasteners 15 is attached to the inner surface of each of the strips 14.

(Operation and Effect of the Invention) Since the present invention is as described above, the back support plate 6 composed of the frame plate 3 and the net plate 5 can be mounted on the back support surface of the Zach main body 1, so that the back and the Zach main body can be carried. The backrest plate 6 is interposed between the backrest surfaces of the backrests 1 so that the breathability of the backrest plate 6 can sufficiently prevent stuffiness due to sweat on the back. The frame plate 3 is made of a leaf spring 7 having outwardly curved portions 7 ', 7' at both ends on the lower side, and plastic frame portions 3 ', 3' are integrally attached to portions near both sides thereof to form a frame portion 3 '. , 3 '
Between the front surface and the back surface, and the frame portion is curved so as not to be in full contact with the back surface of the Zach body 1 but to be partially in contact therewith. Between the back and back of the
At the intermediate portions of the outwardly curved portions 7 ', 7' and the curved portions of the frame portions 3 ', 3' partially contact and hold the Zach body 1 elastically.
When walking while carrying the backpack, the Zach body does not give a solid, uninterrupted and heavy feeling to the back of the backpack, because the Zach body swings elastically and rhythmically in synchronization with this. The degree of fatigue caused by carrying can be significantly reduced, and the present invention has an effect of sufficiently solving the above-described problems.
